Pioneer Tree Species and Biological Forest Succession

Pioneer Tree Species and Biological Forest Succession Pioneer plant species are the first predictable seeders, adaptable to many conditions and the most vigorous flora to colonize disturbed or damaged ecosystems. These plants readily acclimate to bare soil, have the ability to grow and regenerate and respond vigorously on even the poorest soil sites and environmental conditions. Pioneer tree species are also known for their ability to readily seed or root sprout on bare soil and withstand the rigors of low moisture availability, full sunlight and high temperatures along with poorly available site nutrients. These are the plants, including trees, that you first see after a disturbance or fire in newly forming ecotones during field succession. These first tree colonizers become the initial forest tree component of a new forest. North American Pioneers Common pioneer tree species in North America: red cedar, alder, black locust, most pines and larches, yellow poplar, aspen, and many others. Many are valuable and are managed as even-aged stands, many are not desirable as a crop tree and removed for a more desired species. The Process of Forest Succession Biological succession and often-called ecological succession  is the process whereby disturbed existing forests regenerate or where fallow untended lands return to a forested condition. Primary succession is the ecological term where organisms are occupying a site for the first time (old fields, roadbeds, agricultural lands). Secondary succession is where organisms that were part of an earlier successional stage before a disturbance return (forest fire, logging, insect damage). The first plants to grow naturally in a burned or cleared area are usually weeds, shrubs or inferior scrubby trees. These plant species are often controlled or totally removed as defined in a prescribed forest management plan to prepare the area for higher quality tree regeneration. The Classification of Trees following the Pioneers It is important to know which trees will first attempt to cover the site. It is also important to know usually the most dominant tree species in the region that will eventually take over in the process of biological succession. Those trees that move on to occupy and become the main tree species are known as the climax forest community. The regions where these communities of tree species are dominant become the climax forest. Here are the major climax forest regions in North America: The Northern Boreal Coniferous Forest. This forest region is associated with the northern zone of North America, mostly in Canada.The Northern Hardwood Forest. This forest region is associated with the hardwood forests of the Northeastern United States and Eastern Canada.The Central Broadleaf Forest. This forest region is associated with the central broadleaf forests of the Central United States.The Southern Hardwood/Pine Forest. This forest region is associated with the Southern United States along the lower Atlantic through the Gulf coastal areas.The Rock Mountain Coniferous Forest. This forest region is associated with the mountain range from Mexico to Canada.The Pacific Coast Forest. This forest region is with the coniferous forest that hugs the Pacific coast of both the United States and Canada.

Clinical reflection log 1 - Essay Example Throughout this night, most of the staff and team kept on asking Carey about many things going on in the Unit, in order to double check with her regarding their decisions. On the second night, I was so impressed from what I saw during the reporting time that physicians and nurses join together. I believe this is an amazing way to help all those who are going to work in that shift, and make them aware of what they have, and what they don’t have. Afterwards, there is a designated nurse with the responsibility to assign patients to each nurse, and coordinate the work flow. I also greatly appreciate introduction of a small card that mentioned patient name, case and room number. Which helped nurses to take over patient of another nurse. In a busy day, or for any other reason, handing-over of the card of a patient to another nurse allows her to take care of a patient who is not her patient. Honestly, I am planning to apply this idea to the hospital that I am going to work with in future. I also attended the cesarean section. I observed that there was some miscommunication between nurses and physicians which delayed the state case to enter the operation room. The CNS, Carey, encouraged the primary nurse to speak out her thoughts. After that, the primary nurse talked to the doctor regarding this miscommunication, and that was really helpful to correct the mistake and avoid any similar instance next time. Precisely, this is one of the requirements of WHO Quality Improvement Team Debrief. Afterwards, Carey and I spent time in the Unit’s QS system that shows all patients files, and the CTG that was connected to the mother’s room. The night was quiet, and I noticed that the Unit had the same advanced equipment as in my home country. But there was something amazing. Wherever we went around in the Unit, there was a huge screen to show everyone the CTG, with the mothers and

Americas Next Top Model - Essay Example Description actually evolves as new forms of reality shows emerged. The list could be endless as more and more "audition" types and freak-games sprout. Betts went as far as laying out the basic rules for reality programs as "either elimination of contestants in a high-handed or low-minded procedure, or revelation by a spontaneous uncovering of their flaws, conceits or pettiness," (Betts, 2004) with un underlying message that these kind of shows could be of little, or no relevance to people and persons involved except for some rewards for the winners. Starting out with a gem or a germ of an idea is the first crucial stage of every television or even movie and other performing arts production. How is this going to be done, who, when, how, why. The same thing can be said for "America's Next Top Model." First it was just a flash in the mind. Then, the idea jumped out to a drawing board, until it starts taking a skeleton of a shape, then, it has taken form and meat. Jumping off from the success of "American Idol", the fashion world takes a reality program for its own, run by its supposedly creator Tyra Banks", a supermodel herself. The next step after a germ culminated as an idea is to find out the costs in producing the show. Costing: There are two categories for production cost as the cyber college (2005) pointed out: above the line that pertains to performances and production elements like talent fee, script, music, office services, marketing and promotions. Below-the-line include the physical elements like stage, studio, sets, props, wardrobe, graphics, transportation, production equipment, studio facilities, editing, and the technical personnel that includes the stage manager, engineering personnel, video recording operators, audio operators, and general labor. The specifics now follow: 1. Pre-production costs that include putting up the idea into one solid material of project proposal that includes the script, technical descriptions and production abstract. The process of getting financers and technical backers. Estimate*: $ 800,000.00 2. Location scouting and related travel expenses refers to finding out the best possible area for main production site, in America's Next Top Model case, in a luxurious Los Angeles mansion where the young women contestants may have their own room and move freely, at the same time accommodating the technical staff or crew. Expenses for travel during the rounding off of places and spots are included in here until the final touches and detailing. Estimate*: $ 500,000.00 3. Studio rental includes the budget for venue for the professional appearances where catwalk performances as well as general modeling audition will take place. Estimate*: $ 50,000.00 4. Sets and set construction is the beautification concept where the production design will be applied. This includes the process of making the studio appear like a Victoria's Secret runway, the stage, the judges' table and a background that will evoke the ramp

Marketing Communication Trends - Essay Example This paper is an executive report on marketing communication trends. Network radio, along with television, nationalized magazines, and great metropolitan everyday newspapers appear to have constantly been I existence before. These structures not merely tied the nation together; however, there is strapping substantiation that to a large extent they assisted create the current societal and political civilization. Since each person could, and frequently did, perceive and conceivably hear similar messages at once starting from the 1950s and ending in the 1990s, people created nearly standardized mass media, along with mass marketing civilization (Jain, 2008). Marketing companies created generally demanded goods for these mass marketplaces. Retail distribution structures developed to vend to and via these marketplaces. Marketing communications experts developed plans, agendas, and structures to correspond with these mass marketplaces. Then technology rammed into society and individual wants and requirements. Suddenly customers, who currently had additional information compared to before, started to demand particular products, distribution structures, and communication. What at one time had been known to be a mass marketplace fragmented into thousands of detached, individual marketplaces driven by standard of living, ethnic background, earnings, geography, schooling, sexual category, and any other thing, which makes an individual dissimilar from another (Jaceviciute, 2011). Persons who are over 40 years old, were brought up as verbal correspondents. The prominence was on inscription and reading proficiencies. Persons who are less than forty years, are affiliates of the generation that is visual. This age group was raised on TV, movies, speeches, along with the verbal word. The disparity between the manner in which these two age groups communicate is remarkable. The change from a spoken to a visual

Define Newtons 1st, 2nd and 3rd Laws. How do these relate to an Essay

Define Newtons 1st, 2nd and 3rd Laws. How do these relate to an exercise Give at least 3 examples - Essay Example It states that if a force is exerted on a body with mass m then the body would only accelerate or decelerate in the direction of the relative forces. Hence it can be concluded that F=ma where f is force, m is mass and a is acceleration. A real life example of the second law can be considered when the horsepower of a car is analyzed. If a car has a horsepower of 2300CC then it would move at a great speed. Similarly if the mass of this car is increased then the speed would decrease in the same manner. And lastly if the horsepower of the car is increased without changing the mass then the car would move at an even higher speed. The third law of Newton states that every action has an opposite reaction which would try to oppose the action in real. A real life example of this law can be seen when we are swimming or rowing. It is seen that as we push the water behind the water exerts a force in response which helps us move ahead. Both action and reaction can be seen in this

What do you think comprises reality Term Paper Example | Topics and Well Written Essays - 1000 words

What do you think comprises reality - Term Paper Example We do not have a direct perception of substances in minds, but only a representation of them. What we know is not what is inherent to the substances, but only the secondary and primary qualities. Thus, according to Locke, the substances are bodies, which are material, and souls, which are immaterial. Then there is God. He explains the existence of God, not from inherent ideas, but from sense-experience. Their basic substance is assumed from the perception of physical qualities, since qualities must have a solid basis. Likewise, a spiritual soul is formed from the observation of mental operations. We perceive bodies through sensation and have a lucid and instant idea of our soul by reflection. The outside world is independent of the mind. The presence of real objects is what causes real sensations in us (Tully 53). Locke further says there are interactions between the body and mind, both of which are real beings, resulting in the actions of our bodies and minds. The changes experience d by the soul are as a result of its being acted on by outside bodies. On Locke’s third substance, God, he provides that we shape an idea of God by expanding or taking to infinity the rules and objects of our sensations and reflections. What we experience are existence, extension, knowledge and power. Taking them to infinity is our idea of God (Tully 67). Descartes described a substance as a particular thing. He argues that there are material or physical substances and thinking substances, the mind. The substances have characteristics called modes. Modes of physical substances include their location in time, space, shape and volume. The mode of thinking substances includes ideas, judgments and desires of the subject. Every substance has an essential property. The essential property of a material substance is occupying space and time. The essential property of a thinking substance is thinking. Therefore, having ideas, believing or desiring are ways of thinking, and having a sh ape and volume are ways of occupying space and time. Descartes further divides material substances into finite and infinite. Examples of finite materials are human bodies, plants and earth. Likewise, human minds are finite thinking substances. Adding a third substance, he says God is an infinite substance. Therefore, according to Descartes, there are three types of substances; modes, finite substances, and infinite substance. Descartes views reality as relative and divides them into formal and objective reality. Formal is the kind of reality something possesses by merit of the type of thing it is. Infinite substances, finite substances, and modes possess formal reality in varying degrees. Modes have the least formal reality, followed by finite substances then infinite substance in ascending order. The amount of formal reality contained in something is determined by its dependence on another for its existence. The higher the dependence something has on another for existence, the less the formal reality it contains. Modes depend on finite substances, and in turn finite substances depend on infinite substances for existence (Tully 41). For example, the shape of a ball would not exist without a ball, but a ball could exist without that shape. On objective reality, Descartes contributes that first it is only possessed by representation. This means that it is possessed by things that stand for other things. Basically, these are ideas. Examples of representations
